Perhaps you should try some spelling variations:
cham xuc » chat xuc, cham soc, pham duc
so sach » so sanh, bo sach, co sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
va hanh » van hanh, va thanh, va danh
y nang » ky nang, ly nang, v nang
vi cau » va cau, di cau, viet cau
ve cau » ke cau, va cau, ve cac

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: so sach y nang xa hoi. hieu ve ((cham xuc) or (cam xuc)) va hanh ((vi cau) OR (ve cau)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach y nang xa hoi. hieu ve ((cham xuc) OR (cam xuc)) va hanh ((vi cau) OR (ve cau)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach y nang xa hoi. hieu ve ((cham xuc) or (cam xuc)) va hanh ((vi cau) OR (ve cau)) tre".
• Adding a wildcard symbol may retrieve word variants: so sach y nang xa hoi. hieu ve ((cham xuc) or (cam xuc)) va hanh ((vi cau) OR (ve cau)) tre*.
